This much-loved biennial produces rose-purple or white thistle-like flowerheads, which top the long stems in July and August. It adds a structural element to planting, and is perfect for a sunny wildflower border or wildlife garden where it will act as a magnet to bees and goldfinches, which love to feast on the seedheads. These seedheads also dry really well, so will make handsome additions to everlasting arrangements in the home. Commonly known as teasel, its name refers to the spiny heads that were once used for raising or 'teasing out' the nap on fabrics.
